这个简单的指南将向您展示如何制作Micro-SIM 转SIM 卡套 给iPhone 2G到iPhone 3GS手机适配,以便您可以在旧设备中使用新的iPhone 4 Micro-SIM卡。 此过程会破坏旧的SIM卡。 幸运的是,当你购买一个新的iPhone 4时,他们会给你一个新的SIM卡,并停用旧的,使旧的报废。

  1. 你需要
    • 你需要

      • XACTO刀(切割刀)和良好的切割面板,如切割垫。

      • 铅笔

      • SIM卡卡针或者曲别针

      • iPhone4

      • 旧的GSM SIM卡,来作为卡托。


  2. 从iPhone中取出SIM卡。

    • 将Micro-SIM卡放在旧的SIM卡上,使用铅笔描出 Micro-SIM卡的轮廓。

      • 确保上下两个SIM卡的芯片对齐。


    • 使用XACTO刀来按照您画的线切割。

      • 当施加足够的力来切割塑料时,可能难以控制刀片,所以我建议轻轻地切割几次来形成凹槽。 一旦你有一个正确形状的凹槽,施加更多的力量来切割塑料。 您还可以在顶点使用精细钻头钻出5个导向孔。 这也有助于引刀。

      • 要得到一个很干净的切口,你可以尝试用一个较小的打火机甚至点烟器加热刀的尖端。 热的Exacto刀片很容易以这种方式切入SIM卡,但是您可能需要加热几次,因为热量很快会从刀上散发。

      • 几乎完成后,将SIM卡翻转过来。 你应该可以看到大概的切割轮廓。 为了更干净的切割的效果,请从底部完成切割。

    • 从切口中取出切下来的部分。

    Nice write up! I've done this numerous times. A word of advice and EXTREMELY helpful hint: , permanent double-sided tape." Not the commercial or industrial type but just your regular 3M permanent double-sided tape dispenser type, it comes in yellow packaging and usually a 2-pack. Your welcome, lol!

    • 将Micro-SIM插入到切过的SIM卡的孔中。

    • 如果Micro-SIM装不进去那么你就需要使用刀子切除更多的塑料了。

    • 如果你把孔切得太大,把一块胶带贴在SIM卡背面(没有金色触点的那一侧),把Micro-SIM卡固定到位。 用刀裁掉多余的胶带。

      • 你可能想也想贴一些胶带,即使孔是正确的大小; 这将有助于防止Micro-SIM卡在手机内部松动,防止卡在手机中。


    • 测试一下。 我把Micro-SIM插到iPhone 2G中测试,正常工作!

    • 感谢阅读! 如果您在阅读本指南中有任何问题和建议请与我联系。

    I'm so excited this worked! I used a credit card instead and taped the back to keep everything in place. Worked right away! Thanks for your brilliance.

Just a heads up, this could vary easily ruin your SIM card. Better off buying a SIM cutter, faster & exact results.

I just did this with the miniSIM card from my iPhone 4 (ATT) to my iPhone 3GS. First time it was not sucessful, so I pulled it out and repositioned the miniSIM card and it worked perfectly! (Note: In regards to the first post, this method does DESTROY the full size SIM card, but if you are taking these steps this card is MOST LIKELY deactivated and thus garbage. In no way *should* this harm the miniSIM card.)

This worked for me very well, thank you! I used a knife to cut out the micro-sim card shape on my standard sim card. Using tape to cover the rear worked as well.

Life saver! I dropped my iPhone 4s in water today. I really wanted to be able to use my number still, but have no other phone that takes a micro sim. I also couldn't even use my spare iPhone (3gs) because apparently my old sim card is too old for iPhones. So I was stuck using an old phone and an old number for the day.

On my first attempt at this the sim card kind of broke when I tried to cut into it. Luckily I had another dead sim that I could use, and it worked fine the second time. Now I can have my number and at least be able to use an iPhone.

Thank you!

Worked really well! My iPhone 4 died yesterday and I want to be able to call / be called until I get a new one. Used this manual to convert my micro SIM to a normal SIM for use in a (very old school) sony ericsson. For the people who say that you can ruin your SIM card: that shouldn't be a problem if you use a SIM card that is no longer useable anyway.

MY carrier were giving out the regular sim cards where the micro sim could be removed from it as a pull out!

I saved the cutout & it works perfectly as a SIM adaptor! I might well go back & collect a couple more just in case!

In addition, I taped a piece of scotch tape on the non-connector side so that the micro SIM will sit still in the adaptor & still no problems fitting it back into my iphone 3GS.

Alex - 回复

the un-used regular sized sim card i used had the outline of a micro-sim to it; so i merely cut carefully along the outline, pop out the old sim, then replace the hole with the new sim. paste a sticky tape to the non connector side to keep things in place. trim (carefully) the sides to remove excess sticky tapes.

this trimming is important because its usually a tight fit on the regular size sim slot.

all good.

This worked surprisingly well. I just replaced my malfunctioning HTC One M7 with and old school Iphone 3GS. It is working really well after modifying the SIM card to cradle the microSIM. I found a sharp pair of scissors worked better than an exacto knife.

If you're not wanting to destroy the old sim card then use an old bank card or similar, measure the large sim against the bank card, place the small sim in the correct position on the bank card 'sim', cut the lines and bingo.

I used a credit card and it worked! Thanks.

3M Permanent Double-sided tape works wonders if you don't have a SIM-CUTTER!

Worked great. My GF is no longer sobbing that her phone is dead and I am a hero!

The cuts look like a god-awful mess guaranteed to lead to disaster! Why not spend less than $5 to buy proper gear instead of risking ruining a phone that costs far, far more? Another option is to use a cheap card reader to insert your diy card adapter into and download to pc then upload info to new correct size sim card to go into phone—never put any crap into any expensive equipment!
